If we have colonies on Mars I can't see why we also wouldn't have colonies on the moon if only to support ships going further out into the solar system. Refuelling on the moon makes much more sense than refuelling on earth.
The only way that isn't the case is if we build a space elevator to bring resources up to spacecraft orbit, but if we're at that point I still think we would build colonies on the moon just because, even if it's just at the level of a Saudi Arabian vanity project.
People used to say the same thing about books. There was a lot of moral panic about children sitting inside reading rather than being outside and playing with their friends. Then it was comic books, then it was TV, then it was dungeons and dragons, then it was the internet, now it's chatbots.
If there is some detrimental effect, I would like an explanation as to how it's detrimental, rather than just a lot of hearsay.
